Cisco Catalyst 3850 Series Switches FAQ A. In a Cisco Catalyst 3850 stack, all switches should be at the same image-based license (IP Services/IPBase/LAN Base) level. The active switch license level is considered as the reference, and the member switch licenses are compared against it.. The Cisco Catalyst 3850 comes with a 10/100 Ethernet dedicated management port on the backside of the switch right above the console port. This port is in separate VRF called “Mgmt-vrf.” This is to segment the management traffic from the global routing table of the switch.

Cisco Networking Academy's Introduction to VLANs All used ports are associated with VLANs distinct from VLAN 1 and distinct from the black hole VLAN. It is also a good practice to shut down unused switch ports to prevent unauthorized access. A good security practice is to separate management and user data traffic. The management VLAN, which is VLAN 1 by default, should be changed to a separate, distinct VLAN. To communicate remotely with a Cisco switch for management purposes, the switch must have an IP address configured on the management VLAN.
